Introduction

In this tutorial you will see how to create carousel using Twitter Bootstrap. This may help you to create content slider, image galleries etc.

Usage

<div id="myCarousel" class="carousel slide">
  <!-- Carousel items -->
  <div class="carousel-inner">
    <div class="active item">…</div>
    <div class="item">…</div>
    <div class="item">…</div>
  </div>
  <!-- Carousel nav -->
  <a class="carousel-control left" href="#myCarousel" data-slide="prev">‹</a>
  <a class="carousel-control right" href="#myCarousel" data-slide="next">›</a>
</div>
            

So, you keep items (e.g. images) which you want to present in cyclic order in "carousel-inner" division and navigation of the items are created with "<!-- Carousel nav -->". It uses custom data attributes "data-slide" to navigate to previous and next items.

You must include jquery.js and bootstrap-carousel.js files in the HTML file where you are creating the carousel.

Using Javascript

You may use the following JavaScript code to create carousel.

$('.carousel').carousel()
            

Following is a list of options you may use

  • interval: This specifies the time to delay (in milliseconds) between one slide to another. The value is of number type. Default value is 5000
  • pause: This specifies that cycling of images pauses on mouseover and resumes when you leave mouse. The value is of string type. Default value is 'hover'

You may use the following methods with carousel

  • .carousel(options): You may use an optional options object. The object cycles through the carousel items.
  • $('.carousel').carousel({
      interval: 2000 // in milliseconds
    })
                
  • .carousel('cycle'): If used, it cycles through the carousel items from left to right.
  • $('.carousel').carousel('cycle');
                
  • .carousel('pause'): If used, it stops the carousel from cycling through items.
  • $('#myCarousel').hover(function () { 
      $(this).carousel('pause') 
    }
                
  • .carousel(number): If used, it cycles the carousel to a particular frame (0 based, similar to an array).
  • $("#carousel_nav").click(function(){ 
    var item = 4; 
    $('#home_carousel').carousel(item); 
    return false; 
    }); 
                
  • .carousel('prev'): If used, it takes the carousel to the previous item.
  • .carousel('next'): If used, it takes the carousel to the next item.

There are two events to enhance functionality of carousel

  • slide: When the slide instance method is called, this event is fired immediately.
  • slid: When the cycling through the slides are completed, this event is fired.
